Description

Lifting platform unbalance loading prevents structure that inclines

Technical Field

The utility model relates to the technical field of lifting platforms, in particular to an unbalance-loading anti-tilting structure of a lifting platform.

Background

A common short-distance lifting platform is generally modified by a scissor type platform, the stroke generally ranges from 50mm to 150mm, but a scissor mechanism easily bears unbalanced pressure during unbalance loading, so that clamping is caused to be dead or local abrasion is serious, a common solution is to install four unbalance-load-preventing oil cylinders at four corners of a base, a top plate is installed on the upper portion of the unbalance-load-preventing oil cylinder, the unbalance-load-preventing oil cylinder bears most of pressure during unbalance loading, the burden of the scissor mechanism is reduced, but the oil cylinders are increased, so that the cost is increased, the failure rate is increased, and therefore a simpler structure is needed to prevent the problem caused by unbalance loading.

Disclosure of Invention

The utility model aims to solve the defects in the prior art, and provides an inclined-load and inclination-preventing structure of a lifting platform.

The technical scheme adopted by the utility model for solving the technical problems is as follows:

an unbalance-loading anti-tilting structure of a lifting platform comprises a base, a lifting mechanism and a top plate, wherein a guide structure is arranged on the base, and the top plate is connected with the base through the guide structure; the guide structure of the base adopts two vertical limit guides, one is guide rod guide, namely a guide rod and a guide cylinder which are matched with each other are arranged on the top plate and the base for vertical limit, and the guide structure can also be a slide rail and slide sleeve structure; the second is a guide wheel and guide rod structure, as shown in fig. 1, the guide rod is limited to move horizontally in the horizontal direction, so that the top plate can only move in the up-and-down direction, and the accuracy of moving the goods upwards is ensured.

The base is provided with a slope, and the lifting mechanism is arranged on the base in a matching way through the lifting roller and the slope; the oil cylinder is connected with the base and the lifting frame, the extending direction of the oil cylinder is the ascending direction of the slope, and the lifting frame moves forwards and upwards along the slope under the pushing of the oil cylinder. Be equipped with the supporting roller on the crane, the roof passes through the supporting roller to be connected on elevating system, and the crane upwards moves forward, but because the limiting displacement of leading wheel, the roof can only upwards move, and the supporting roller makes relative slip easier between roof and the crane.

As shown in the figure, the optimal number of the slopes, the lifting rollers and the supporting rollers is 4, so that the number of the vulnerable parts is small, and most of pressure is concentrated on one or two lifting rollers and the slopes during unbalance loading, so that large pressure cannot be applied to the vulnerable parts.

The utility model has the beneficial effects that:

1. the mode of adopting slope and lift gyro wheel, the wearing parts is less, and most pressure concentrates on a certain or two lift gyro wheels and slopes during the unbalance loading moreover, can not cause great pressure to wearing parts.

2. The existence of supporting roller and leading wheel truns into ascending removal with the ascending removal forward for the goods can only be vertical upwards, and supporting roller makes the relative motion between roof and the elevating system more smooth moreover, can not appear the dead condition of card.

Detailed Description

In order to clearly explain the technical features of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings. The following disclosure provides many different embodiments, or examples, for implementing different features of the utility model. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and procedures are omitted so as to not unnecessarily limit the utility model. The terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the utility model and for simplicity in description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be construed as limiting the utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
